JavaScript、NS_ERROR_DOM_BAD_URI 的 ArcGIS API：拒绝访问受限 URI

Question

我正在遵循此指南：

https://developers.arcgis.com/javascript/jshelp/intro_agstemplate_amd.html

我正在使用他们在教程中使用的 Web 地图 ID：1a40fa5cc1ab4569b79f45444d728067

但是，当我运行我的代码时：

var map;
require([
"esri/map",
"esri/arcgis/utils",
"dojo/domReady!"
], function(Map, arcgisUtils) {
    arcgisUtils.arcgisUrl = "file:///C:/Users/Bryan/Desktop/gis.html";
    arcgisUtils.createMap("1a40fa5cc1ab4569b79f45444d728067 ", "mapDiv").then(function(response) {
        map = response.map;
    });
});

我收到以下错误：

NS_ERROR_DOM_BAD_URI: Access to restricted URI denied

在教程中他们说了以下内容：

To access a web map from a portal outside of ArcGIS Online, reference the arcgisUrl property and set the path to your portal URL before calling the createMap() method: arcgisUtils.arcgisUrl = "http://pathto/portal/sharing/content/items";

但是什么是门户 URL？我的门户是什么 URL？

Answer 1

我们将逐步解决以上问题：

首先你应该知道你的网络地图 ID 1a40fa5cc1ab4569b79f45444d728067 你正在使用它的 public 或私人。我的意思是每个人或创建它的创建者都可以访问它。

如您所见，我可以在全球范围内访问此 ID，这意味着它不是私有的，因此您无需添加门户 url

（以下是访问您的网络地图的两种方式，只需替换下面 urls 末尾的网络地图 ID）。

以上Webmap ID的项目详情： click here to see the details of webmap id.

地图查看器中的 Webmap ID： click here to see webmap id in map viewer.

仅当 webmap id 未与所有人共享时才需要门户 url。

Portal URL: 每当您注册 arcgis.com 之后，它都会创建一个独特的门户 url (为每个用户安装 Portal for ArcGIS 的服务器名称 )。这个唯一的url只有在ifwebmap/item不共享给所有人的时候才需要配置。在这种情况下，它会自动 "arcgis online default portal url".

现在转到 this online sample 并在那里替换您的网络地图 ID。它会正常工作。

运行代码：

require([
        "dojo/parser",
        "dojo/ready",
        "dijit/layout/BorderContainer",
        "dijit/layout/ContentPane",
        "dojo/dom",
        "esri/map", 
        "esri/urlUtils",
        "esri/arcgis/utils",
        "esri/dijit/Legend",
        "esri/dijit/Scalebar",
        "dojo/domReady!"
      ], function(
        parser,
        ready,
        BorderContainer,
        ContentPane,
        dom,
        Map,
        urlUtils,
        arcgisUtils,
        Legend,
        Scalebar
      ) {
        ready(function(){

        parser.parse();

//if accessing webmap from a portal outside of ArcGIS Online, uncomment and replace path with portal URL
       //arcgisUtils.arcgisUrl = "https://pathto/portal/sharing/content/items";
        arcgisUtils.createMap("1a40fa5cc1ab4569b79f45444d728067 ","map").then(function(response){
          //update the app 
          dom.byId("title").innerHTML = response.itemInfo.item.title;
          dom.byId("subtitle").innerHTML = response.itemInfo.item.snippet;

          var map = response.map;



          //add the scalebar 
          var scalebar = new Scalebar({
            map: map,
            scalebarUnit: "english"
          });

          //add the legend. Note that we use the utility method getLegendLayers to get 
          //the layers to display in the legend from the createMap response.
          var legendLayers = arcgisUtils.getLegendLayers(response); 
          var legendDijit = new Legend({
            map: map,
            layerInfos: legendLayers
          },"legend");
          legendDijit.startup();


        });


        });

      });
